Man, here's what you do. Bolt on some old racing slicks and put the car in front of their house, pump up the line lock, and givem' a smoke show they'll never forget.
Screw your neighbors. If it's your property and if you aren't going off it, or you aren't causing any problems, then I don't see what there deal is. They probably just want to start some sh** with you, man. They probably have nothing else better to do anyways.
**** them as far as I'm concerned, and good luck at the race.
